/kernel/trunk/ |
Update page fault handlers to distinguish between different access modes that had caused the page fault. |
|

/kernel/trunk/ |
Implemented mips memcpy (copy from gcc builtin memcpy). |
|
| 1288 |
6602 d 8 h |
jermar |
/kernel/trunk/ |
Complete implementation of copy_from_uspace() and copy_to_uspace()
for amd64 and ia32. Other architectures still compile and run,
but need to implement their own assembly-only memcpy(), memcpy_from_uspace(),
memcpy_to_uspace() and their failover parts. For these architectures
only dummy implementations are provided. |

/kernel/trunk/ |
Added support for IRQ notifiactions.
- seems to work correctly on ia32, amd64
- the mips kbd probably lowers interrupts when the char is read from
the port, we will have to find a way how to deal with it. |

Make ia64 and sparc64 compile again.
Fix ia64 to set up inits in arch_pre_main(). |

init tasks must be registered before main_bsp() |

Add task_create_arch() for all architectures. |
|
| 1184 |
6624 d 5 h |
jermar |
/kernel/trunk/ |
Move arch/thread.h to arch/proc/thread.h on all architectures.
Replace ARCH_THREAD_DATA with new thread_arch_t arch on all architectures.
Similarily, add task_arch_t arch on all architectures.
On amd64 and ia32, grow the TSS segment by 64K + 1B to support IO port
permission bitmap. For the same reason, define per task IO port permission bitmaps
on ia32 and amd64. |

Initialize ARCH_THREAD_DATA on all architectures.
On ia32 and amd64 this fixes bug caused by uninitialized TLS pointer. |

PIC running. |

Small atomic #include and typedef changes. |
|

Define atomic_t only once in atomic.h
Change the encapsulated counter type to long so that it supports negative values as well. |

Keep $K1 register for use as a thread local storage pointer on MIPS. |

/kernel/trunk/ |
Cleanup of spinlocks, now compiles both ia32 and amd64 with
and without DEBUG_SPINLOCKS. Made spinlocks inline.
Moved syscall_handler to generic (it was identical for ia32,amd64 & mips32).
Made slightly faster syscall for ia32.
Made better interrupt routines for ia32.
Allow not saving non-scratch registers during interrupt on ia32,amd64,mips32.
Aligned interrupt handlers on ia32,amd64, this should prevent problems
with different instruction lengths. |

Cleanup of mips
- inline register reads
- better fpu disable/enable - global settings is automatically propagated to task
- fast syscall |

Updated stackarg macros for mips32.
Mips32 stack aligned on 8 bytes boundary. |

Redefine semantics of unary atomic operations.
Add test to verify that an architecture understands the semantics correctly. |

Nicer ia32 interrupt handlers and structures holding interrupted context data.
Unify the name holding interrupted context data on all architectures to be istate. |

Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader. |
|
| 938 |
6656 d 1 h |

/kernel/trunk/ |
Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention. |
|

Added lazy fpu context allocation.
- threads that don't use fpu, don't get allocated fpu context
- fpu context alignment on AMD64 nicely disappeared |

Some arc bios tweaks. Wanted to print configuration data, but
the ARC seems to return strange values.
Newport graphics card does not seem to be easy to port, give up now. |
|

Fixes in memory allocator
- proper kernel blacklisting, when kernel not loaded on page boundary
- correct zone adding in zone list (how could this work??) |

6686 d 3 h |

/kernel/trunk/ |
Make use of one unused bit in PTE formats of amd64, ia32 and mips32 to store 1 in valid mappings.
This helps to distinguish valid entries from not present entries with 0 content (i.e. not present
entries with PFN 0 and other bits cleared). |
|

Remove WAKEUP_IPI stuff.
Make it possible to use PAGE_GLOBAL on ia32, amd64 and mips32.

Cleanup o frame allocator.
Removed early_malloc & initial heap.
